Definitions

  • the invention relates to a lifting apparatus, comprising
  • a device of the generic kind is known from DE 43 26 673 A1. Similar and further solutions are shown in DE 697 19 001 T2, in FR 2 757 441 A1, in DE 101 32 350 A1 and in DE 102 57 108 A1. With such a device for example parts of vehicles can be conveyed along an electric suspension track, wherein the height above ground of the part which has to be transported can be adjusted. As tension element chains or ropes are used which are wound on respective rope drums or a lifting unit for chains to adjust the height over ground of the part of the vehicle. For the stabilisation of the lifting element relatively to the supporting carriage a separate device is used. This pre-known solution has detrimentally a relatively high installation length and has a relatively high weight. Furthermore, the position of the lifting element is varying with the lift height.
  • EP 1 794 078 B1 shows EP 1 794 078 B1. Also this device has a relatively high installation length and a high weight. The design is relatively complex and offers a plurality of possibilities for adjustment. Furthermore, a relatively elaborate manufacturing and assembly of the device as well as a poor accessibility for the purpose of maintenance are detrimental. Also here, as in the case of the pre-known solution, the lifting device as well as the stabilisation device are separately designed.
  • a first drive is present for driving of the at least one first winding apparatus and a second drive for driving of the at least one second winding apparatus
  • the first drive comprises a drive motor which drives at least one shaft via an conical gear mechanism, preferably via a bevel gear, which shaft drives a roller of the first winding apparatus via a gear mechanism element
  • the second drive comprises a drive motor which drives a roller of the second winding apparatus via a spur gear, a parallel-shaft gear or a planetary gear mechanism.
  • the width is at least 200 times, specifically preferred at least 300 times and very specifically preferred at least 500 times of the thickness. However, often the width is at least 1,000 times of the thickness.
  • tension element a band-shaped structure should be employed which is correspondingly differentiated to the pre-known solutions with ropes of chains, eventually also with small belts.
  • tension elements for example wide flat belts and other plane designed and sheets which can be wound respectively are used, which are especially flexible,
  • the tension elements do not have a constant width along the whole used height to meet requirements with respect to the design.
  • the tension elements are enlarged in the width especially at one of their ends.
  • the tension elements do not have a constant thickness along the whole used height. So, the tension element can for example be reinforced at the fixation of the end and thus thicker as in the remaining region,
  • the basis for the mentioned width-thickness ratio is insofar the plane base material of the tension element.
  • a further preferred embodiment of the invention provides that the width of the tension elements is selected in dependence of the outer dimensions of the supporting carriage and the lifting element respectively. Accordingly the width of the tension elements is at least 50% of the outer dimensions of the supporting carriage and/or of the lifting element at the location of the tension element, Respective optimal values for the width of the tension element are between 50% and 100% of said outer dimension. Especially at the use of drums with integrated drive the upper region can be easily realized.
  • Preferably four winding apparatus are present, wherein respectively the roller of two winding apparatus have axes of rotation which are arranged parallel to another and wherein the axes of rotation of the rollers of two winding apparatus are perpendicular to the axis of rotation of the rollers of the two further winding apparatus,
  • the first drive for driving of two winding apparatus and the second drive for driving of two further winding apparatus are present.
  • Another preferred embodiment of the invention provides that three winding apparatus are present, wherein two rollers of the first and second winding apparatus have axes of rotation which are arranged parallel to another and the axis of rotation of the roller of the third winding apparatus is arranged perpendicular to the axis of rotation of the first and second winding apparatus.
  • the rollers of the first and second winding apparatus and the roller of the third winding apparatus form preferably a H-shaped structure in the top plan view.
  • the tension elements consist according to a preferred embodiment of the invention of textile material, especially of a textile sheet, or of metal, especially of a metal sheet or of a netting.
  • the present invention concerns thus a device for lifting and stabilizing of loads, especially a hanger for vehicles or parts of vehicles, comprising a supporting carriage (upper frame) as well as a lifting element (lower frame) which is arranged below it, a load reception device for receiving the load which is adjustable in height by means of preferably wide belts or textiles (tension elements) which are fixed at the lower frame and which can be raised or lowered by means of at least two (respectively due to safety reasons preferably at least three) rollers (drums)—which are in the case of three or four rollers are especially arranged orthogonally to another.
  • the lower frame is stabilized in the position relatively to the upper frame due to a membrane effect of the belts and textiles respectively which is namely obtained that the belts and textiles respectively (tension elements) have a sufficient width which goes far beyond the pure lifting function and so no further mechanical stabilisation device, like scissor type supports, telescopes etc., is required to stabilize the relative movement of the lower frame to the upper frame in horizontal direction.
  • the tension elements can also be realized by a wide thin metal band or metal mesh.
  • the lower frame can be supplied with a changing adapter which allows the reception of different hangers.
  • rollers lifting drums
  • one or more spur gears, parallel-shaft gears or planetary gear mechanisms and/or with one or more conical gear mechanisms for their drive is possible. By doing so it can be done without a separate conical gear mechanism.
  • the lower frame does not comprise otherwise due to its concept any installations in the inner region, as the case may be a lifting ramp which is dimensioned accordingly can be brought in between the reception traverses whereby maintenance work at the lifting apparatus can be facilitated significantly—especially in distinction to the pre-known solutions.
  • the axes of rotation of the rollers of said winding apparatus are arranged perpendicular to another,
  • said orthogonality is given in one of the views, especially in the top plan view of the device.
  • the axes include an angle of only 87°.
  • FIG. 1 shows in perspective view a lifting apparatus which is movable arranged along a path in horizontal direction, wherein one lifting element (lower frame) is arranged relatively to a supporting carriage (upper frame) in a lowered position,
  • FIG. 4 shows the top plan view onto the arrangement according to FIG. 3 .
  • FIG. 5 shows in perspective view an alternative embodiment of the invention in the depiction according to FIG. 3 .
  • FIG. 7 shows in perspective view the lower frame of the lifting apparatus with a compensation of the length of the belt according to a first embodiment
  • FIG. 8 shows in perspective view the lower frame of the lifting apparatus with a compensation of the length of the belt according to a second embodiment
  • a lifting apparatus 1 which is arranged movable in a horizontal direction along a track 2 being a rail. With the lifting apparatus 1 parts can be conveyed in horizontal direction wherefore the lifting apparatus 1 is moved along the track 2 . Said movement can occur actively or passively, i.e. motorised or not motorised rollers can be provided in the region of the track 2 .
  • the lifting device 5 comprises four winding devices 10 , 11 , 12 and 13 which comprise each a driven roller 14 , 15 , 16 and 17 , wherein each roller 14 , 15 , 16 , 17 winds or winds-up a tension element 6 , 7 , 8 and 9 when it is rotated around its respective axis of rotation a 1 , a 2 , a 3 and a 4 respectively (see for this FIG. 4 ).
  • a first drive 18 which comprises a drive motor 21 which drives a conical gear mechanism 22 .
  • a drive motor 21 which drives a conical gear mechanism 22 .
  • the conical gear mechanism 22 two shafts 23 and 24 are driven by which in turn each one gear mechanism element 25 and 26 is driven; the gear mechanism elements 25 , 26 are preferably chain or belt drives.
  • the rollers 14 and 15 respectively are rotated synchronous.
  • a second drive 19 which comprises a drive motor 27 by which a spur gear, a parallel-shaft gear or a planetary gear mechanism (all schematically indicated by 28 ) is driven.
  • the spur gear 28 drives in turn two gear elements 29 and 30 —again preferably designed as chain or belt drive—by which the rollers 16 and 17 are rotated synchronous.
  • the two drives 18 and 19 are again synchronized relative to another wherefore a synchronisation element 20 is provided.
  • a shaft section is provided therefore which connects the two drive motors 21 and 27 with another so that their shafts can only be rotated synchronous.
  • FIGS. 5 and 6 and alternative embodiment of the invention is shown.
  • the difference to the above described solution is that here instead of four winding devices only three of them are provided, namely the winding devices 10 , 11 and 12 with its respective rollers 14 , 15 and 16 .
  • the axes of rotation a 1 and a 2 of the rollers 14 and 15 are parallel arranged to another; the axis of rotation a 3 of the roller 16 is arranged to them (in a top plan view) perpendicular so that a H-shaped structure for the three rollers 14 , 15 and 16 is given when the same are viewed in the top plan view. Beside this the design corresponds to the above explained arrangement.
  • a special and subsequently described embodiment of the invention deals with a statically determined compensation of the length of the belts which can be provided as an option at the described elevating device.
  • the elevating device 1 (lifting hanger) consists—as explained—of the supporting carriage 3 (upper frame) and the lifting element 4 (lower frame).
  • the lower frame is held by the tension elements 6 , 7 , 8 , 9 .
  • the winding devices are meaningful arranged in the upper frame 3 .
  • Different length of the belts can result due to tolerances of thickness of the tension elements (lifting belts), due to differences in the diameter of the winding drums, due to small errors in the transmission etc.
  • FIG. 7 The solution which is shown in FIG. 7 is subsequently denoted as type A, the solution which is shown in FIG. 8 is denoted as type B.
  • FIG. 9 a detail of the arrangement is shown. Thereby, the above described concept is provided in the FIGS. 7 to 9 , wherein three tension elements 6 7 , 8 (indicated in the FIGS. 7 and 8 only with respect to their location) are wound on rollers in H-shaped arrangement.
  • the tension force of the tie rods 35 , 36 increases proportionally with the tension force of the belts of the transversal belts 6 , 7 and thus of the right-turning torque.
  • the left-turning torque is proportional to the tension force of the longitudinal belt 8 (see FIG. 5 ).
  • the equilibrium of the eccentrics 32 is kept at a certain partition of the lifting load between the longitudinal belt 8 and the two transversal belts 6 , 7 .
  • the longitudinal belt 8 receives the half lifting load. The other half is divided between the two transversal belts 6 , 7 .
  • the rocker 37 , 38 of the transverse arranged end roll of belt 39 , 40 ensures that the longitudinal belt 8 is loaded symmetrically, even if for example the two transverse belts 6 , 7 wind slightly asymmetrically or lengthen slightly different due to an asymmetric load distribution in longitudinal direction. Nevertheless, longitudinal forces which act onto the longitudinal belt 8 can be received via the transverse rigidity of the longitudinal belt.
  • the be rods 35 , 36 are connected each with one rocker 37 , 38 of the transverse rollers 39 , 40 .
  • the transverse rollers are rotatable at the assembly process for winding the transverse belts. About three windings are normal to relieve via friction the fixation of the end of the belt at the end rolls of belt. After the assembly process the roller 39 , 40 are firmly screwed with the rocker 37 , 38 ,
  • This design allows that the ends of the belt are fixed by means of several windings or via loops of the belt. The first maintains the whole strength of the belt while loops weaken the belt at the location of the connection (seam, damping).
  • the tie rods 35 , 36 are directly connected here with the rotatable supported transverse arranged end rolls of belt 39 , 40 .
  • the tangentially arranged transverse belts exert so a torque onto the end rolls of belt. Those torques create each a tension force in the tie rods 35 , 36 .
